HENRY E. MERRILL, OF AKRON, OHIO.

MACHINE FOR MAKING BROCK-RIMS.

SPECIFICATION forming part of Letters Patent No. 398,640, dated February26, 1889. Application filed November 20, 1888. Serial No. 291,362. (Nomodeh) To all 07mm it muy concer/1,:

Be it known that l, HENRY E. Marittimi, a

citizen of the linited States, residing at Akron,

in the county of Summit and State ot Ohio, i have invented :t certainnew and useful Ma chine for Making (lundi-Rims, of which theVtiiiliowing is a slieeilieation.

My invention has relation to imin'ovements in ('levices for forming arim about the upper 1 outer et e of creeks when in a plastic state, thebodies ol' which havebeen pressed through :in annular oritiee, and is animprtjlvetnent ot" the invention t'or whieh l was granted Unitedy#States Letters Patent NojlttT/ttti, Januarvl.

thereon when closed, and consisting of two semicireular pieces hingedtogether at one end and provided with a clamp at the other, by whiehthey mayv be looked. In the inner upper corner of this ring is a channelterminating at the base in a quadrioircular groove, y, of the samediameter as the groove in the pulley e. In the upper face are two rods,i', arranged to turn therein and with their upper ends bent at a right'angle.

In operation the arm E heilig removed, the shaft Il, disk C, and drum D,properly adj usted, are placed in the green crock, the edge of which isthen eut accuratelyv in the plane otf the drum I). The open ring,` G isthen placed about the crock, being suspended at the proper height bytherods `z', which are turned inward and rest on the drum D until A the twohalves are locked together and clamp similar letters of referentieindicate like parts, 3

and pulley.

vFigure l, is a central vertical section of a crock, showing myinvention applied thereto, i

the part inside the eroek shown in elevation and the surrounding` ringin similar section with the eroclr'; and Fig. 2, perspective of 'theouter ring partially opened.

The part ot' the maehine within, the erocl; l

A consists of a central shaft, B, attached to the center of a disk, C,and passing through t the center of a wide-faced pulley or drum, D,

which is adjustable thereon by means of a tially as shown anddescribed.A

setserew, d, said disk and drum being of the same diameter as theinterim of the crock.

On the shaft B, above the drum D7 is joute naled an arm, E, bearing atits outer end a pulley, e, having in its face a semieircular l groove ofthe size and shape of the upper half of the desired rim, the inner edgeof said pulleybeing arranged to run Close to the outside of a channel inthe ring, hereinafter desoribed.

The elements thus farare similar to those shown in the patent beforereferred to.

Outside the crock is a ring, G, which fits the crock sutiieiently toretain themselves thereon, when the rods are turned outward. The arm Eis then placed on the shaft B and revolved bythe handle F, therebypressing the soft edges of the Crock down until the hub of the pulley erests on the drum D, forining a complete rim in the grooves of the ringI. In a machine for forming rims on eartl1- entire vessels while theyare in a plastic state, the combination, with a shaft arranged to standand be supported in the axis of the vessel and a radial arm carrying arim-forming wheel arranged to revolve about said shaft, of an openingring arranged to be clamped about said vessel and having a mold to formthe lower part of the rim, substan- 2. The combination, with the cutring G, having a mold for the lower part of the crockrim, of the bentrods it, arranged to be turned therein and support said ring,substantially as shown and described.

In testimony that I elaiin the above I hereunto set my hand.

HENRY E. MERRILL.
